Description:
	This program allows easy GPU voltage adjustments on GPUs with volte
	rra-based voltage regulators and it uses the award-winning and criti
	cally acclaimed RivaTuner for these adjustments.

	WARNING! By using this program, you agree that the author is NOT
	responsible for ANY consequences as a result of using this program.
	You, the user, are liable for any damages occured. Be a smart overc
	locker and monitor those temperatures and voltage levels!

Compatibility:
	Most GT200 GPUs are supported, some G92 GPUs, and all RV770/790 GPUs
	above 4870, and several custom PCB boards. If you aren't sure, just
	try it and see if it works ;)

	Tested on: Visiontek Radeon HD 4870 X2, BFG GeForce GTX 295,
		   SAPPHIRE Radeon HD 4870 X2, ATI Radeon HD 4890,
		   ASUS EAH4870 X2 Tri-Fan, and more!

Requirements:
	- RivaTuner (v2.24 is the minimum version)
	- A compatible GPU with volterra-based voltage regulators
	- Latest GPU drivers
	- A modern Windows-NT based operating system (XP and above). Both x86 and x64 are supported.
	- Microsoft(R) Visual C++ 2008 Runtime (x86), can be found here:
  	  http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf
 	- Microsoft(R) .NET Framework v2.0 (minimum), can be found here:
  	  http://www.microsoft.com/downloads/details.aspx?FamilyID=0856EACB-4362-4B0D-8EDD-AAB15C5E04F5

Instructions:
	First, you need to put the full path to RivaTuner in RivaPath.txt (with a
	trailing backslash [\]).

	I designed this program with automation in mind, so most settings should
	already be correct. But if they aren't you can correct them. For example,
	in the GPU Information section, if the selected voltage is not the "3D"
	performance voltage, please select the correct one. You can change the
	"Current GPU #" drop-down to anything you want, it's for your information.
	What you set under "GPU Voltage Tuning" for "Number of GPUs" will affect
	which GPUs' voltages get set. Again, it should be automatically detected.
	Voltages available range from 0.8625v to 1.6000v, so be careful what you set!

	If all of the voltage VIDs are displayed as "0xff", then you selected a
	non-existant GPU under "Current GPU #".

	* Note: Do not have RivaTuner running prior to running GPU Voltage Tuner, it
	  will refuse to work properly.
	* Also, if you are unsure whether the automatically detected and selected vo
	  ltage is correct, you can check by loading up a full-screen game with GPU-Z
	  or RivaTuner logging the GPU voltage in the background. If it is incorrect,
	  simply select the correct load voltage.
	* If you wish to set voltages higher than 1.45v, you'll need to unlock higher
	  voltages through the Advanced Settings menu by right-clicking the voltage
	  drop-down.

I made this for even easier use than the other programs introduced by other fine members of XS. It works more automatically as well.

Enjoy! Please test it!

killer, but remember it only works with volterra equipped cards.

IE not the gay 285's lol.

I have been using GPU Tool from TPU for the 4890 cards, works well but you need to have something like furmark running when you set voltages so the card is in 3d clock mode and keeps voltages for benching

Link to tool?

I am already maxed on voltages anyway, and it does not work for the 4850 :(

Going to have to hard mod mine to pass 800 MHz
